Good to know
Developers often paste API keys, tokens, customer data and internal code into online tools without thinking about where that data goes. Many “free” developer websites send everything to their servers and log it. Color Converter runs completely in your browser using standard web APIs, so it is safe for production data. It also works offline once loaded, which makes it handy on slow connections or restricted networks.
